Title: Electronic refrigeration control system
Inventor: ODEN KENNETH W
IPC: F25D21/00
Filed: 1995-10-11
Granted: 2003-09-23
Abstract: The present invention is direct to a system and method for electronically controlling the refrigeration and/or heating of the product storage compartment in a vending machine.   The system includes a temperature sensor for sensing the temperature in the product storage compartment,  and a door sensor for sensing whether the door is open or closed.  The control method includes the steps of activating a defrost mode, which is a timed period with no heating or cooling activity, when the door to the vending apparatus is open.   The defrost mode is also activated  whenever  the  cooling  element  has  been  running continuously for several hours.   Further, the control method includes a step of cycling the cooling element "on" whenever a predetermined high temperature is reached.   When the cooling element is "off" for more than 6 hours and the predetermined high temperature has not been reached, the heater is turned "on" to prevent the products in the vending machine from freezing.

Abstract: A rail tie plate (410,420,440,460,478) comprises two elements each provided with a rail flange shoulder (414), a downward leg (421) and a lateral projection (422) whereby the tie plate can be installed on a plate member (21, 121, 221, 321) of a slotted steel tie (20, 120, 220, 320) by insertion of the projection (422) of each element into a respective slot and rotation of the element inwardly and downward. A tie plate (410, 420, 440, 450, 460, 478) having longitudinal shoulders (414) is provided with a downwardly facing abutment surface such as provided by an opening (424) laterally through each shoulder (414) on which a rail clip (430, 470, 482, 489) engages to bear on an upper side of the rail flange (416). Rail rollover is avoided by transferring rotational forces to the plate (410, 420, 440, 450, 460, 478) through the engagement of the clip (430, 470, 482, 489) on the shoulder (414) and resisting such rotational force at the connection between the tie plate (410, 420, 440, 450, 460, 478) and the tie (20, 120, 220, 320). A steel tie for incorporation in a rail track has a horizontal oblong rectangular plate member (21, 121, 221, 321) for connection transversely of the rail, and a web (23) or webs (123, 223, 323) extending vertically on the underside of the plate member (21, 121, 221, 321) and spaced inwardly from its longer sides. A ballast engaging plate member (33, 41, 133, 233, 333) may be connected on the tie on its underside and faces generally transversely of the rail or ends of the plate (21, 121, 221, 321) may be bent downwardly.

Granted: 1999-11-09
Abstract: An apparatus and method for perforating and fracturing subterranean formations to enhance fluid production.  At least one unlined punch charge is loaded into at least one punch charge carrier (26), and the void spaces in the punch charge carrier are filled with sand. The punch charge carrier is assembled with at least one perforating charge carrier (32), loaded with at least one perforating charge, and a means for detonation.  The assembly is positioned in a well containing a pressurized fluid adjacent the interval to be perforated and/or fractured, and the charges are detonated.  The one or more punch charges create one or more apertures in the punch charge carrier, allowing sand to enter the well and be carried by the fluid in the well into the perforations and/or fractures created by the perforating charges and the pressurized fluid. The sand scours and/or props the perforations and/or fractures.

Title: Detectably labeled dual conformation oligonucleotide probes, assays and kits
Inventor: TYAGI SANJAY
IPC: C12N15/09
Filed: 1996-05-10
Granted: 2011-10-18
Abstract: Unimolecular and bimolecular hybridization probes for the detection of nucleic acid target sequences comprise a target complement sequence, an affinity pair holding the probe in a closed conformation in the absence of target sequence, and either a label pair that interacts when the probe is in the closed conformation or, for certain unimolecular probes, a non-interactive label. Hybridization of the target and target complement sequences shifts the probe to an open conformation.  The shift is detectable due to reduced interaction of the label pair or by detecting a signal from a non-interactive label.  Certain unimolecular probes can discriminate between target and non-target sequences differing by as little as one nucleotide.  Also, universal stems and kits useful for constructing said probes. Also, assays utilizing said probes and kits for performing such assays.

Title: Removable vertical fall arrest device
Inventor: ATKINSON GEOFFREY FRASER
IPC: A62B1/14
Filed: 1995-03-31
Granted: 2005-06-21
Abstract: A vertical fall arrest device is disclosed which combines in a single unit the means to arrest a fall, the capability to automatically traverse intermediate support means provided along a safety line, and ease of attachment to or detachment from the safety line at any point throughout its length. In the attached condition, in which a safety line (30) is captured in retaining recess (60), the device is always in a ready state to lock-on to the safety line in the event of a fall. The device is removed from the safety line by depressing release catch (44) against spring pressure and at the same time pulling wheel (42) in a direction away from body member (41). Movement of the wheel must also be effected against biasing pressure. This combined operation creates an opening for withdrawal of safety line (30). When the external forces are relaxed, internal springs (47a and 47b) ensure that both the wheel (42) and the release catch (44) return to their fully locked conditions.

IPC: C07K16/18
Filed: 1995-11-13
Granted: 2006-07-04
Abstract: This invention provides methods useful in aiding in the diagnosis of Alzheimer's disease. The methods involve measuring the amount of amyloid-.beta. peptide (x- >=41) in the cerebrospinal fluid of a patient. High levels of the peptide generally are inconsistent with a diagnosis of Alzheimer's. Low levels of the peptide are consistent with the disease and, with other tests, can provide a positive diagnosis. Other methods involve measuring the amounts of both A.beta.(x -. gtoreq.41) and tau.  Low levels of A.beta.(x- >=41) and high levels of tau are a positive indicator of Alzheimer's disease, while high levels of A.beta.(x->=41) and low levels of tau are a negative indication of Alzheimer's disease.

Title: Chair locking mechanism
Inventor: DESNOYERS CHARLES
IPC: A47C3/03
Filed: 1998-04-07
Granted: 2008-05-13
Abstract: A locking mechanism for chairs such as gliding and rocking chairs comprises a toothed rack for connection to the chair seat with the rack oriented generally in the direction of movement of the chair seat relative to the base and the teeth extending along the rack and facing towards a pin that is carried in the base. The rear end of the rack is pivoted to the chair seat and the front end of the rack is connected to a pivoting linkage arrangement operated by a lever at the side of the chair seat. Operation of the lever is effective to swing the toothed rack from a retracted position to a lowered position wherein the locking pin is engaged by a registering tooth in the rack. The attitude of the chair in the locked position will depend upon the position of the locking interengagement between the pin and the toothed rack.
